JOHN J. BERRY, OF INDIANAPOLIS, INDIANA.

TAN K SU PPLY-VALVE.

SPECIFICATION forming part of Letters Patent No. 5,722,644, dated July 10, 1894. Application filed .Tune 5,1893. Serial No. 476,627. (No model.)

- the following is a specification.

' My invention `relates to new and useful improvements in tank supply valves for use yparticularly in connection with flushing water tanks of water-closets.

The object of my invention is to provide a supply valve that will automatically operateto close the valve when the tank is full and open said valve when the tank is emptied of its contentsgand to provide means whereby the supply of the infiowing water will be directed or deflected downwardly to avoid splashing and to cause a rotation of the valve to present different portions of its bearing surface to the valve seat. I accomplish these objects by means of the valve and the valve mechanism illustrated in the accompanying drawings in which similar numbers of reference designate like parts throughout the several views.

Fig-ure l. is a broken sectional view of a supply tank and showing my supply valve in section, and taken through the line A. B. See Fig. 4f. Fig. 2. is a similar section of the same showing the valve in its open position. Fig. 3. is4 an end elevation of the valve, and Fig. 4.. is a plan ofthe same, with` the valve operating mechanism rem0ved.`

The supply valve is composed of the annular valve seat 1, having a central opening rounded at its edge to form a bearing for the ball valve 2, preferably of rubber, or otherV Y yieldingor elastic material,'the collar 3, the' hollow threaded stem 4, the vertically proj ecting guide standards 5, the toggle supporting between them.

ends 6, and the downwardly inclined deflecting wings or ears 7, all of which are formed in one piece, and secured vfirmly to the bottom of the supply or flushing tank, 8, by means of the binding nut 9, which clamps the bottom of said tank. The guides or standards have their inner guiding surfaces concave to receive the cylindrical sliding piece 10, which is adapted to slidevlongitudinally The sliding hold-down piece has its top end slottedor recessed diametrically which is pivoted lon the pin 13, `secured in said sliding piece.L The top link 14., of the toggle is pivoted on the pin 15, secured on to receive the end 1l, of the bottom toggle 12,

the standard ends 6, and the toggle pin 16. i

The stem of the ioat 17, is firmly secured in the socket 18 formed integral on the bottom v toggle 12. p

Itis obvious that when the 'supply of water in the tank 8, is exhausted till the iloat 17 descends in the direction of the arrow shown in Fig. l, and when the sliding piece 10 has moved upwardly into the position shown in Fig. 2, the ball valve 2, is released and is'free to move upwardly by reason of the pressure of the iniiowing water which forces said valve upwardly against the bottom concave surface of the said sliding piece 10.

The main feature lofkmy invention is embodied in the arrangement of the valve and its actuating mechanism which is automatic in its action. By means of this special arrangement of toggle a great'amount of pressure is brought to bear on the valve to hold it on its seat against a great pressure of a resisting uid andl to effectually close said valve and avoid leakage.

It is clear that the end of the sliding piece -may be formed to close or seat on the valve fnewv'andluseful, and desire to cover by Let- ',ters Patent of the United States therefor, is-

. Inj a tan-k' supply valve, the combination '.withV an annular'valve-seat having a central 'opening'and vertically projecting standards formed ,integral thereon and on opposite sides of said valve opening, of a cylindrical sliding piece-having its top end bifurcated, said piece adapted to slide longitudinally upwardly and downwardly between said standards, aY sphere or ball between said sliding piece and valve seat and adapted to moveupwardly and downwardly between said standards, fixed and downwardly inclined deflecting earsor wings connecting said standards IOO In testimony whereof I have hereunto set my hand in presence of two subscribzug wit- Io nesses.
